Title: Finder device
Inventor: KOIKE KAZUMI
IPC: G03B17/02
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent the deviation of finder field caused by the positional deviation of an eye in a finder device though the cost of the device is low. SOLUTION: This finder device 12 is constituted of a concave objective lens 25, a convex ocular 26 and a blind type light shielding member 27 provided in front of the lens 25. Ten blades 31, for example, fixed at specified intervals in the frame 30 of the member 27 are juxtaposed so that their longitudinal direction is a horizontal direction and a vertical direction to a finder optical axis L1. The inclination of each blade 31 to the optical axis L1 is set to be along a finder optical path going toward an eyepoint A. Since a light beam made incident on the device 12 is not parallel with the blade 31 when the eye is deviated from the eyepoint A, vignetting is caused in the finder field, which is not easy-to-view.  By deciding the position of the eye so that the vignetting is not caused in the finder field, the eye is naturally put at the eyepoint A, so that a user looks in the normal finder field where a photographing range is shown in a non-parallax state.

Title: Method and device for ask communication
Inventor: SATO TOMIO
IPC: H04L27/02
Filed: 1993-11-17
Abstract: PURPOSE:To obtain high reliability with comparatively simple configuration by controlling the gain of a receiver corresponding to the level of a pre-carrier and returning the gain to the state before control when no carrier is received for a prescribed time. CONSTITUTION:A pre-carrier is sent from a transmitter prior to a remote control signal and data are sent after that. A receiver detects the arrival of the carrier and a time detector generates carrier reception time information simultaneously and gives each signal to a control part. When the carrier is consecutive for a predetermined time, the control part generates a trigger signal to an ATT control part, which generates a DC voltage corresponding to the received electric field strength to provide an output to an ATT part. The ATT part controls a drain-source current of a FET based on the voltage to control the gain of a high frequency amplifier. Furthermore, when the reception of the carrier is intermitted for a predetermined time or over, the gain of the receiver is restored to the original gain.
